UNITED STATES PATENT OFFICE.

AMOS BREED, OF LA HARPE, ILLINOIS.

IMPROVEMENT AIN CLACK-VALVES FOR WOODEN PUMPS.

Specification forming part of Letters Patent No. 137,126, dated March 25, 1873.

To all whom it may concern:

Be it known that I, AMos BREED, of La Harpe, in the county ofHancock and State of Illinois, have invented certain Improvements in the Bearing and Attachment of Clack- Valves for Wooden Pumps, of which the `following is a specitication:

My improvement consists in a raised seat or bearing-plate for the clack-valve, made of iron or other suitable material, with a neck or band on the under side of the valve-seat,

4to be driven into the wood at the upper end of General Description.

A is any ordinary wood-pump tubing. B is the raised valve-seat. G is the clack-valve.

D is the neck or under-band of valve-seat, shown as driven into the wood until the flange of B has a fair bearing on end of wood. E E are screws or nails to secure the leather of clack-valve and the valve-seat to the tubing.

vF F are holes cast in the. valve-seat to admit E to tubing.

This valve-seat, cast the proper size to suit the bore of tubing, may be used for any Wood pump by driving the neck or band D into the tubing, not into the bore. The upper edge of valve-seat is so rounded as to prevent the lodgment of any substance under the leather ot' valve, thus causing the escape of the water. Should nails, gravel, or an y such substances enter the pump from above or be drawn through the clack-valve from below they will be deposited, on the end of tubing outside the rim or raised valve-seat and below the clack-valve.

I claim- The raised rim a ofthe valve-seat B in connection with the neck or under-baud D driven into the end of tube A, substantially as shown, and for the purpose of securinga water-tight joint, and preventing the lodgment of substances under the clackvalve; and I disclaim all other parts.

AMOS BREED..
